EACTORIEs GROVE, TEXAS, TEXAs, A oORrORATioN or DELAWARE Ass'reNoR To` ASSOCIATED COTTON-GIN MACHINERY Application filed September 16, 1929. Serial No. 392,914.

rIhis invention relates to cotton gin machinery, and the primary object thereof is to provide a new arrangement of parts whereby the customary saw gin ribs of such linachines are dispensed with. l

In a former application for Letters Patent of the lUnited States, filed by the applicant herein, there was disclosed a working embodiment illustrating the same principle involved in this present application.

Applicant now seeks to improve certain parts in a cotton gin construction as referre to above, whereby, in addition to the eradication of the regular gin rib there are provided a multiple series of saws disposed on an inclined plane. Operably associated with the saws are certain other cooperating parts, including principally v a stripper, and conveying'means to carry away the lint and. seed, the latter means being in common use in machines of this sort.

The combined result is an increase in caacity and in general utility in a cotton gin of the class hereinbefore referred to.

The invention will be more clearly and readily understood from a perusal of the following detailed description, taken in connection with the accompanying drawings, and wherein: v

Figure 1 is a sectional view of a cotton gin,

illustrating the improved gin.

Figure 2 is a detail sectional viewof a saw assembly, illustrating their mode of disposal on a shaft. Y L

Figure 3 represents a side elevational view of a spiked roller shaft, one of which is disposed between each series of saws, and

Figure 4 is a fragmentary detail perspec tive view of a stripper.

1 denotes a base 2 and rear walls 2', enclosing the gin mechanism. It should be here understood, in this connectiomthat Vthe gin emdrawings, cluding a construction,

Having amore detailed reference to the l* housing or casing, 1n-v bodying the principle involved, is .capable ofV may be employed that'will support the shafts 4 on an inclined plane. Bearings 4 arev provided for the shafts. 2

On each shaft 4 are disposed in close formation, a pluralityof saws 5. These saws are of the regular gin saw type and between each saw is a spacer element 6, which, however, enables the saws to lie fairly close together, there being only a fractional space between the saws. The shafts 4 are made to revolve byasuitable pulley arrangement in the same direction'as indicated by the ar- Successive series of saws are close enough together to prevent any cotton seed from passing between the teeth, but are spaced far'enough'apartto permit the lint to pass through as it is combed and pulled from the seed.

Disposed between the top-most saws and the curvature of the casing 1 is a stripper of well known construction comprisingV a drum r7, upon which are arranged the angle irons or strips 8, the drum mounted on a `shaft 9-all of well known construction.

Below the stripper is a cotton seed conveyor 10. There are also roller brushes 11, disposed on the drums 12, the latter mounted on the shafts 13, dofing the lint fromthe saws. lint is collected in the flues 14 drawn into an air conduit 17, by means of air suction means, not shown.

The cotton is fed into the gin through the chute 18, feeder rolls 19 beingv disposed in the throat of the chute. Between the sloping The cotton for brushing or l and 15 andV wall of the casing 1 and the saws is arranged Y `l in spaced formation several spiked rollers 20. Y Y

rlhese rollers lie between adgacentsaw se-V ries, and keep the cotton `moving fromwone series of saws to the other.

In operation of the machine, cotton is fed intothe chute 18, assisted by the lfeeder rolls 19, andA falls upon the saws. One of the advantages of thegin saw arrangement as carried out in this invention is the increase in output by assembling a plurality ofsaws in series, and on an inclined plane. Where only two shafts of saws are used (as in formerapplication referred to) the upper serieslof saws must vrevolve fasterpthan those.k below. l

vfio

il j ciently to permit passage of lint between the 5 collected iny theflues le and' into the air suction conduit 17.

the O'inninof instrumentalities but a nr Y 7 passage of cotton seed, said gin-v must revolve faster than the one recedin" u l it. For instance7 in the dra-wing in Figure l, the lowermost saw lOO R. P M'., the next saw series is turned'at 200 R. P. lvl., the third Series at 400 R. P. M.

`and the topinost series of saws are revolved at 800 RP, M. ln the lorder then,lit will be clear that the ginning at the bottom, be thrust outwardly toward the sloping wall of the casiiigin the direction of the rotation of the saws, faster than the cotton on the lowermost saws. rlhis gives a combing, carding and pulling effect on the cotton in removing the seed therefrom. The same effect is had between the next two saw series, since each higher shaft carrying its complelnent of saws rotates at The cotton is thus carried upwardly and kept moving iii and out from. the saws by the ro'll ers 20. vThe lint removed from the-seed is l5 and passes of the rotation,

carried on the shaft Qstrips the cotton seed from the uppermost saw series and theseed is deposited inthe conveyor 10.
